Abstract: Technology for analyzing interactive content is disclosed. In one example, a method is used for providing influence analysis of the interactive content. The method can include determining a base influence score of a first user based at least on types and quantities of the first-user-generated content items. The base influence score can be dampened to account for self-referential content items within the first-user-generated content items. The method can include determining an interactive influence score of the first user based on other-user-generated content items descending from the first-user-generated content items. The method can include combining the base influence score and the interactive influence score to create an influence score of the first user.

Abstract: A method for recording images of small particles to detect cracking includes feeding particle samples to a place for image recording, illumination a particle sample from at least two directions simultaneously, the illumination occurring with different light wavelengths for each direction, recording partial images of the illuminated particle in different channels, which are sensitive to different wavelengths, and comparing the different partial images to analyze the particle sample. Each partial image shows the particle sample illuminated from one direction by the channel recording only one of the different light wavelengths.

Abstract: A method and device for optical measuring of small particles for analysis of the quality of the particles. A sample-feeding carrier is adapted to take up particle samples in sample holders and transport the particle samples to a place for optical measurement. A mirror-supporting means follows the movement of the carrier and has mirrors matching the sample holders. A device illuminates a particle sample when positioned for optical measurement and a detector, which is sensitive to electromagnetic radiation, records a result of optical measurement of the illuminated particle sample. A mirror reflects the particle sample, so that a mirror image thereof stands essentially still seen from the detector, when a measurement is being recorded, owing to the fact that the mirror image of the particle sample falls on a center axis of the movement of the mirror-supporting means.

Abstract: A method for recording images of small particles to analyze the quality of the particles, especially to detect any cracking in the particles, comprises the steps of feeding particle samples which each comprise at least one particle, to a place for image recording, illuminating a particle sample from at least two directions simultaneously, the illumination occurring with different light wavelengths for each direction, recording an image of the illuminated particle sample with the aid of an image-recording means, which records partial images of the particle sample in different channels, which are sensitive to different wavelengths, and comparing the different partial images to analyze the particle sample. Each partial image shows the particle sample illuminated from one direction by the channel recording only one of the different light wavelengths.
